To announce the 2017 Jaguar XF, Jaguar recently had stuntman Jim Dowdall drive the car over Canary Wharf in London along a pair of high wires. The car was aided in its 787-foot over-water crossing by custom grooved wheels, a safety tether, and a curious medallion-shaped weight. According to Jaguar, the stunt was “the world’s longest high-wire water crossing by car.” To skip the rather long-winded introduction and see the crossing itself, start at the 3:45 mark.
